john stones 1 - Moderator Posted October 30, 2014 Share Posted October 30, 2014 I could be wrong again Kev, but I think rudder top is solid and it's tapes that give an impression of a rib being there ? been some photos added by David Williams in resources John Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted October 30, 2014 Author Share Posted October 30, 2014 Saw those John. Using picture 1 of David`s set and a 3 view it looks to me like there are ribs under there. I too could also be wrong. Does anyone know for certain? Kev Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 30, 2014 Share Posted October 30, 2014 The leading edge looks pretty much aluminium over a rib structure then open structure ast it goes past vertical. I have the benefit of having Davids pics at full resolution Cheers Danny Quote Link to comment Share on other sites More sharing options...
David P Williams Posted October 30, 2014 Share Posted October 30, 2014 Yes exactly right Danny - I gave it a good feel . From memory again (not always reliable as we have found out!) there is a mass balance weight in the nose of the fin top, as there definitely is in the nose of the elevator tips. You can see in the photo the vertical line where the aluminium stops. Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted November 1, 2014 Share Posted November 1, 2014 That APS drawing shows the wash-out, different root and wing-tip,sections as well as the down-thrust very clearly. In those days Aeromodeller would regularly do a full-size aircraft feature with detailed three-views of the highest standard. I'd like to see RCME do that.

Kevin Fairgrieve Posted November 1, 2014 Author Share Posted November 1, 2014 After much thought and mulling over all the comments about the true "scale" of the plan I have decided to go with push rods for my ailerons and flaps. With the effort gone into getting the hinges from SLEC via Danny an the going into will it won`t it territory, I bottled it. So push rods and bell cranks! Never done them before!! All previous models have had servo`s in the wing. Q1 How on earth do you work out where to mount the plate, height wise. Q2 How do you then determine where the hole`s need to go in the rib, again height wise. I want to put the hole`s in place before commencing the build! Q3 I am going to be adding a small scale feature in the wing tips. Lights! These will obviously need to be routed through the ribs also. Where would the best place be to put a third set of holes, without destroying the strength of the ribs? Kev Quote Link to comment Share on other sites More sharing options...
Nev Posted November 1, 2014 Share Posted November 1, 2014 I'm putting in tip lights too Kev, going to run the wires through the ribs in front of the main spar. That bits sheeted, putting in a small hole isn't going to weeken it. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted November 1, 2014 Author Share Posted November 1, 2014 That was my thinking also. 3 rulers. Top one shows lights. Middle one aileron route. Bottom one (small ruler) flaps. Nothing glued yet, still getting my head round this!! Not going anything silly in the light department. Just some cheap ones from Hobbyking. Wires will need extending, but for this ex TV engineer no problem. Turnigy R/C LED Lighting System.

Danny Fenton Posted November 1, 2014 Share Posted November 1, 2014 Kevin if you are not comfortable with bellcranks then don't use them. Unless you are really spot on they are difficult to fit without too much slop. With modern lightweight servos then don't feel you have let yourself down by not using bellcranks. I wish I hadn't been so pig headed in wanting to use them Try them on the flaps and see how you get on. Having said that if you cannot get them to work you can always rip the cranks out and fir a pair of servos Basically with the cranks you generally fit them so that the link to the control is as perpendicular possible. On mine, because of the height of the bellcrank "stack" that meant fitting as low as i could in the rib. Remember I have 3/16 hard balsa wood rails under the ply plates. If you look at my ribs the permagrit needle files have had to be used to alter the holes in the ribs to alleviate any binding, but then filled in with small scrap pieces to slop the piano wire flexing and "bouncing" with Vibration. If you want the dimensions I have used then I can let you know what they are exactly Cheers Danny Quote Link to comment Share on other sites More sharing options...
Dylan Reynolds LaserCraft Services Posted November 2, 2014 Share Posted November 2, 2014 Tbh are wing ribs going to be weakened tht much by just adding in a hole? they arn't load bearing, and only there to hold the aerofoil shape to the wing? I would have thought you would be pretty safe with a hole for wiring, it isn't going to be that large is it? Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted November 5, 2014 Author Share Posted November 5, 2014 It is Wednesday so it must be weekly update time. Following on from my decision to go with the plan with respect to control links I have finally put glue to wood. Well actually quite a bit of glue to wood. All the above is glued and drying as I type. Nice and straight. Used aliphatic for the centre section and trailing edge and CA for the ribs and false trailing edge .

Kevin Fairgrieve Posted November 9, 2014 Author Share Posted November 9, 2014 There will be no weekly update this coming Wednesday! Why? Well SWMBO and I find out on November 21st of one or perhaps even both of are to be made redundant. November the 21st is the date set for us to be told our fate, (but we could still remain in our current positions for anything from 3 months to a year!!) So we have said sod it and have booked a late deal to Madeira for a week. See you all a week Monday. I suspect by then that Danny will also have converted his to RTP. Anyway this is where I am at. Mulling over the centre section and the possibility of adding sheer webs. Kev Quote Link to comment Share on other sites More sharing options...

Colin Leighfield Posted November 9, 2014 Share Posted November 9, 2014 Kevin, fingers crossed that things turn out ok for you both.

Danny Fenton Posted November 9, 2014 Share Posted November 9, 2014 RTP now theres an idea Have a great time Kev, and hope you can concentrate on a pina collada or two and not worry about what is or isn't waiting at home As Nev says that wing looks really nice, well done Cheers Danny Quote Link to comment Share on other sites More sharing options...
Nigel Day Posted November 10, 2014 Share Posted November 10, 2014 I hope that you have/had a great time Kev. Madeira's a lovely place and plenty to see. Get over the to the far side of the island if you can. The trip over/around is worth it. Fingers crossed for the 21st.. Quote Link to comment Share on other sites More sharing options...

Kevin Fairgrieve Posted November 18, 2014 Author Share Posted November 18, 2014 Had a great time away. Thanks for all the positive comments, cheered me up no end. Going to take me a couple of days to read through all the threads to catch up, but am aiming to do that soonest. Then on with the build. If you have never been to Madeira, then put it on your list. Stunning landscape and rugged terrain. Kev Quote Link to comment Share on other sites More sharing options...

Kevin Fairgrieve Posted November 21, 2014 Author Share Posted November 21, 2014 D Day today. The basics are as follows. In my department there are two managers. One of us will no longer be required. However there will be vacancies in other departments. The process for selection will start early January 2015. We will have a one to one with the top boss man and HR. We will then have to do several on line assessment and technical aptitude tests. Following that we will go for another one to one to find out how we did in the tests and discuss which job we would like (if any). This whole process will take until late April or early May 2015 to complete. Any one not getting (or wanting) one of the offered jobs will not be able to take redundancy until late June 2015. So as I see it, I may remain in my current position - 50/50 chance. I may be offered an alternative position, or I may be made redundant in June 2015. There are possibilities that I may even get a better higher paid job (but not sure I want all the "effluent" that goes with it.) So still none the wiser I am going to crack on with the build. Albeit at a slightly slower pace as we approach the silly season that for us is Christmas. I think I have told you all before NEVER EVER work in retail. First things first though I am going to invest in a larger bench. Kev Edited By Kevin Fairgrieve on 21/11/2014 18:56:07 Quote Link to comment Share on other sites More sharing options...
